stuff snipped

The common thing that seems to be done nowadays is to tie the two ends
of the cords with a half hitch before connecting the plug and socket.

While I realize you're not condoning the practice, I've done that in the
past but now I use "clamps" designed to keep long cords coupled. The
reason? Tying the extension cords in a half-hitch causes the cords to bend
180 degrees where the wire exits either the plug of one cord or the socket
of the mating one. I've had the insulation break from the stress and reveal
the invidual wires.

Since then, I use a barrel-shaped enclosed connector for the cord in the
driveway that occasionally gets run over. It also *tends* to reduce water
reaching the two couple cords.

But there are lots of other designs.

In a pinch where I might be up on the roof and DEFINITELY don't want a
disconnection while up there, I might still half-hitch cords together. (-:
